>I do put the name like this: FUNB-04102001.TXT. I rename the file the same way in some cases. There are others where I have to name the file something else ao that another program that I have no control over can use it. This is usually when I run into this problem. Have any idea how to find duplicates int ehtables if thus does occur?

Just a thought..

Could you add some kind of marker into the file to say you have processed it? one which would not affect the other system that's importing it?
maybe a CHR(254/0) after the end of file marker?

As far as finding duplicates, there are lots of ways of doing this (search on UT) but I usually find that pulling the file into a holding table then working on it record by record is the best way.
